This is just a poly capacitor.

The way you read the identification is:

335 = 3300000 picofarads (0.000003300000 pico = 10 minus 12- there are five zeros before the 33) or 3.3 microfarads (micro = 10 to the minus 6, you search it by microfarads)

the second part is the working voltage: 250VDC.

You can use any capacitor that is within the range. Let's say you have a capacitor that's 350VDC and fits in your in you pcb, just as long as it's over the 250V of the original it's fine.

I have put the parameters in on Mouser which I use often and you can just buy one part from them. If you click on a cap you think will work the listing will show size, type etc. This is not an electrolytic is has no direction and can be installed either way. It's polyethylene (PET)
